Common name: Green Clown Goby

General information

The Green Clown Goby, Gobiodon atrangulatus, is a small, peaceful fish that is well-suited for reef aquariums. Its vibrant green coloration and unique behavior make it a favorite among aquarists. This species is known for its ability to change color, often becoming darker or lighter depending on its mood and environment.

Care

Green Clown Gobies are hardy and can adapt to a variety of tank conditions, making them suitable for both novice and experienced hobbyists. They require an aquarium with plenty of live rock for hiding and spawning. These gobies are not aggressive eaters, so care should be taken to ensure they receive adequate food, especially when housed with faster, more aggressive feeders.

Reproduction

In the aquarium, Gobiodon atrangulatus may spawn in the crevices of live rock. The male guards the eggs until they hatch. Breeding these gobies in captivity can be a rewarding experience for the dedicated hobbyist.

Symbiosis

While not involved in the classic anemone-fish symbiosis, Green Clown Gobies have a fascinating relationship with certain corals. They often reside within the branches of Acropora corals, which provide them with shelter and protection. In return, the gobies may help keep the coral free from parasites and algae.

Habitat

Green Clown Gobies are found in the Western Pacific, from the Great Barrier Reef to the Ryukyu Islands. They inhabit coral-rich areas of lagoons and outer reefs, often associating with branching corals like Acropora.
